Question

The normal boiling temperature of benzene is 353.24 k, and the vapor pressure of liquid benzene is 1.00 × 10⁴ pa at 20.0°c. calculate the following (you can take the atmosphere pressure as 101.325 kpa)

ΔH mvaporization

Answer 1

The student is seeking help to calculate the enthalpy of vaporization for benzene but did not provide enough information to perform the calculation using the Clausius-Clapeyron equation.

Step-by-step explanation:

The student is asking about calculating the enthalpy of vaporization (ΔHmvaporization) for benzene. Unfortunately, the student did not provide the necessary information to calculate ΔHmvaporization.

Typically, one would use the Clausius-Clapeyron equation to relate the vapor pressure of a substance at two different temperatures to its enthalpy of vaporization. In this instance, the student has only provided the vapor pressure at one temperature (20.0°C) and the normal boiling temperature, which is not enough information for calculation.

For a complete calculation, we'd need the vapor pressure at another temperature or the actual value of the enthalpy of vaporization. The normal boiling point for benzene is the temperature at which the vapor pressure equals atmospheric pressure, which is typically considered to be 101.325 kPa. Since we do not have the required information to calculate ΔHmvaporization, we cannot solve the problem as stated.
